[ character ]
Character identification of this product curling into a regiment, withered green. Rhizome short, under the most fine fibrous root, the plant has the branch of size, basal leaves caespitose, rosette; leaf blade elliptic or broadly ovate, long 2-5.5cm, apex obtuse, base cordate, margin shallowly dentate. Scapes8-19cm long, some with white silk wool, have a strip of bract. Capitate inflorescences solitary, diameter 2cm, small plant inflorescence edge flower, purple red, central flower tubular, yellow, tubular flowers plants only. Achenes fusiform, two ends of contraction. Gas micro, taste spicy, bitter.
Microscopic identification of root transection in epidermal cells:1 column, often show brown or light brown, the most visible hair or its residue, red to pale brown or brown. Cortex parenchyma thickness, sometimes visible crack ( root of the thicker portion ); endothelial cell layer1, Kay's point. Pericycle cells in1 columns. Monocyclic type vascular bundle, phloem bundle often 4-5; primary xylem often 4-5prototype, secondary xylem small amounts ( root coarse part). Center for the smaller medullary.
Ye Heng: section on epidermal cell, each of the 1 columns, thick cuticle; holes in lower epidermis; visible multicellular non-glandular hairs or medium ( lower epidermis Rondeau ), non glandular apical cell very narrow, twisting distortion. Mesophyll leaves no palisade and sponge tissue differentiation, only on subepidermal cells arranged in a more compact, neat; both sides of the mesophyll tissue often connected to main veins at the upper epidermis. The main vein of subepidermal visible about 1columns of cells comprising the collenchyma ( or less). The main vein vascular circular, xylem and phloem is visible above the collenchyma.
